Hypothalamus ( His, 1893a ) : His introduced the term hypothalamus here, but included the preoptic region (Swanson, 1976b, pp. 229-235) of the hypothalamus (Kuhlenbeck, 1927) in the telencephalon (His, 1893b); pp. 159-162.

Thalamus ( TH ; His, 1893a ) : The dorsal (Barclay, 1803) topographic division of the interbrain (Baer, 1837); the ventral (Schulze, 1893) topographic division is the hypothalamus (Kuhlenbeck, 1927). The macrodissected adult human thalamus was clearly illustrated by Vesalius (1543; see translation by Singer, 1952, Figs. 4-8) and the term as defined here was introduced by His (1893a, pp. 161-162). It includes the traditional epithalamus, dorsal thalamus, and ventral thalamus of Herrick (1910, pp. 494, 498); also see Kuhlenbeck (1927, Ch. 9) and Jones (1985, p. 87).
